Managing Services

Web services can be deployed in the ESB profile of WSO2 Enterprise Integrator (WSO2 EI) to facilitate various integration use cases, such as using proxy services for message mediation and data services for exposing datasources.

The following topics explain how you can manage your services using the management console :

Accessing the service dashboard

Follow the steps below to access the dashboard of a service.

1. Log in to the management console and select Services > List under the Main menu. 
2. The Deployed Services page appears, which lists out all deployed services. 
   
   
3. Click on a service to view its dashboard. See the section given below on managing a service using the dashboard for more information.

Accessing the service groups dashboard

Follow the steps given below to access and manage service groups.  

1. Log in to the management console and select Services > List under the Main menu. 
2. In the Deployed Services page that appears, click the deployed service group(s) link to access the groups.
   
3. The Deployed Service Groups window opens. Click a group to go to its dashboard.  
4. The Services Panel lists all the services included in the group. For example,
   

Managing a service using the dashboard

When you click a service on the Deployed Services screen or the Service Groups dashboard, the service dashboard will open. You can then use the following functions available on the dashboard:

Getting the service endpoints

The Endpoints section on the service dashboard displays the endpoint URLs that can be used to access the service. Each service has two endpoints by default. Typically, the endpoint URI is of the following format: http://{host ip of the server}:{server port}/services/{service name}.

Trying the service

When you click Try this service, it will direct you to a page that displays all the operations available for the service. For operations that take arguments, you will see primitive argument type fields. The values specified in these fields will be passed to the operations. For no-argument operations, you will only see the button that has the same name as the operation. Click Send to invoke the service operation. The return value immediately appears in the response text area.

Generating a client for the service

The Generate Client option is provided by the wsdl.tools feature of the WSO2 feature repository.

Using the WSDLs: WSDL 1.1 and WSDL 2.0 

Opens XML configurations. The WSDLs describe the operations that the service expose, the structure of the XML that is sent and received by each operation, and how to communicate with the service to retrieve the XML content. By default, six different types of endpoints are deployed. Each of these endpoint types are represented by the WSDL 2.0 <endpoint> elements of the service, and by the <binding> elements to which these endpoints refer. The default six types of endpoints are as follows:

• SOAP 1.2 over HTTP
• SOAP 1.1 over HTTP
• Plain old XML/REST over HTTP
• SOAP 1.2 over HTTPS
• SOAP 1.1 over HTTPS
• Plain old XML/REST over HTTPS

The URLs for the WSDL files of the service can also be appended by concatenating the endpoint URL of the service with the following strings:

• ?wsdl2 : WSDL 2.0 description of the service
• ?wsdl: WSDL 1.1 description of the service

Viewing statistics

The Statistics panel provides statistical information about a service as follows: Request Count, Response Count, Fault Count, Maximum Response Time, Minimum Response Time, Average Response Time. It also provides a graphical view of the system response time.

Editing a service

The service Specific Configurations section allows you to apply modifications to your service. The available options will depend on the type of service. See the following topics for instructions relevant to each service type:

• Editing a proxy service.
• Editing a data service.
